1. Whirl Up a Quick Pesto (Beyond the Classic)

The most obvious answer to what to do with leftover basil leaves is pesto, but don’t stop at the traditional pine nut version.
 
You can swap pine nuts for walnuts, almonds, or even sunflower seeds for a nutty twist.
 
Throw in a handful of spinach or arugula to stretch your leftover basil leaves even further.
 
Add olive oil, garlic, parmesan, and a squeeze of lemon, then blitz until smooth.
 
This pesto freezes beautifully, so it’s a great long-term solution for leftover basil leaves.
 
Spoon it over pasta, spread it on sandwiches, or dollop it onto roasted veggies.
 

2. Infuse Some Basil-Infused Oil or Vinegar

If you have a bigger bunch, making infused oil is a brilliant way to handle what to do with leftover basil leaves.
 
Gently heat olive oil with the leaves, but don’t let it boil, just warm until fragrant.
 
Let it cool, then strain out the leaves and store the oil in a clean bottle.
 
Basil-infused oil is perfect for drizzling over salads, brushing on bread, or finishing soups.
 
Likewise, you can stuff leftover basil leaves into a jar of white wine vinegar and let it sit for a week.
 
That basil vinegar is amazing for salad dressings and marinades.
 

3. Freeze Them for Future Cooking

Freezing is hands-down the easiest answer when you’re short on time and wondering what to do with leftover basil leaves.
 
You have two great options: freeze whole leaves or puree them with oil into ice cube trays.
 
For whole leaves, lay them flat on a baking sheet, freeze for an hour, then transfer to a bag.
 
For the cubes, blend the leftover basil leaves with a little olive oil and pour into trays.
 
Once frozen, pop the cubes into a zip-top bag and use them in soups, sauces, or stews all winter.
 
This way, you’ll never throw away leftover basil leaves again.
